AC Adapter can’t supply power for laptops
My wife's laptop doesn't react to having an laptop AC adapter plugged in, but it can still run off of battery. (I charge her battery in my laptop and all is well, but that gets old quick.)Any ideas as to what could be causing this?
I popped it open and didn't notice anything popped or burnt, all the traces seem in tact and the capacitors are happily sitting there without so much as a bead of capci-juice running down the side.I'm hoping to be told "oh, that problem, just shake it this way, spray some air here, and off you go", but so far HP has just been telling me it is a $400 job and I have to wait a month to get it back.
Is this a new laptop or an older one? After two and a half years, my laptop's AC adapter went bad. There are stress points at various points on an adapter. Go to a local retailer w/ a decent return policy and buy a universal power adapter. They usually come with a transformer, an AC plug, and another cable that goes to the computer. It should come with a variety of plugs for various laptop brands.
Buy one (I use a Targus adapter) which is capable of putting out an equal or greater power output as the one my wife has. It should say it on the adapter itself. I don't remember how I determined my laptop's power requirements. I think I took it from the laptop battery's voltage and amperage stats.Anyways, if this doesn't work, then you can rule out the AC adapter and figure out what to do next. But changes are that your AC adapter will fail sooner than the laptop's motherboard power plug header.
